Background technique

Energy storage containers mainly rely on the energy storage equipment system installed inside to store electrical energy. The generator set of the energy storage container has the advantages of beautiful appearance, reasonable structure, good sealing, and can work in harsh environments. It also has the advantages of good soundproofing and convenient lifting. Energy storage containers can be used in power construction, medical emergency, petrochemical, mining and oil fields, hotels, vehicles, roads and railways, etc. In addition, energy storage containers can also be used for the collection and storage of natural resources into electrical energy, or temporary power supply facilities.

In the use of energy storage containers, fire safety is a crucial evaluation criterion. In the fire protection system of the energy storage container, the partition valve generally uses a solenoid valve as a partition valve to protect the partition. When the fire protection system is started, the solenoid valve needs to be opened and the pipeline of the fire protection system is connected to spray fire water. However, since the space of the energy storage container is very compact, if there is a problem with the solenoid valve, it will cause the solenoid valve to be inconvenient to replace, and the space required for the installation of the solenoid valve is relatively large, resulting in the space occupied by the battery in the energy storage container being squeezed, which is not conducive to improving the energy density of the energy storage container; at the same time, the solenoid valve needs to be powered on for a long time, and its cost is relatively high.

Please refer to Figures 1, 2 and 4. In this embodiment, the sub-control valve includes a valve body 100, a sealing diaphragm 200 and an electric explosion drive device. A fluid flow path is formed inside the valve body 100. The fluid flow path has an inlet 103 and an outlet 104. The central axis of the inlet 103 is arranged at an angle with the central axis of the outlet 104. The sealing diaphragm 200 is sealed and arranged in the fluid flow path, and divides the fluid flow path into a first flow channel 110 and a second flow channel 120. The electric explosion drive device is installed on the valve body 100. The output end of the electric explosion drive device is driven and connected with a piercing member 31. The piercing member 31 is located in the second flow channel 120 and is arranged opposite to the sealing diaphragm 200. The electric explosion drive device can be electrically connected to an external control unit 400, and the external control unit 400 can send a start signal to open the electric explosion drive device and drive the piercing member 31 to approach and pierce the sealing diaphragm 200.

The sub-control valve in this embodiment divides the fluid flow path of the valve body 100 into a first flow channel 110 and a second flow channel 120 through a sealing diaphragm 200. The valve body 100 is also provided with an electric explosion drive device. The output end of the electric explosion drive device is driven to be connected with a piercing member 31. When the electric explosion drive device receives a start signal from an external control unit 400, the electric explosion drive device ignites and explodes, driving the piercing member 31 to penetrate the sealing diaphragm 200 from the second flow channel 120, so that the first flow channel 110 and the second flow channel 120 are connected, realizing the connection of the fluid flow path and the opening of the sub-control valve. The sub-control valve in this embodiment has a simple and compact structure. The sub-control valve can be opened by only using the electric explosion drive device to drive the piercing member 31 to penetrate the sealing diaphragm. It has a short response time and a low manufacturing cost. When the sub-control valve is applied to the fire protection system of the energy storage battery box, the space occupied by the sub-control valve can be reduced, thereby improving the energy density of the energy storage battery box.

Please continue to refer to FIG. 2 , a limiting portion 111 is provided in the first flow channel 110, a sealing gasket 210 and a fixing member 220 are also inserted in the first flow channel 110, the sealing gasket 210 abuts against the limiting portion 111, the fixing member 220 is detachably connected to the inner wall of the first flow channel 110, and the sealing diaphragm 200 is sandwiched between the fixing member 220 and the sealing gasket 210. The inner wall of the first flow channel 110 is provided with an internal thread, the outer peripheral wall surface of the fixing member 220 is provided with an external thread, and the fixing member 220 is threadedly connected to the inner wall of the first flow channel 110. The sealing diaphragm 200 configured in this way can be firmly clamped on the limiting portion 111 by the fixing member 220, and when the sealing diaphragm 200 needs to be replaced, it is only necessary to remove the fixing member 220 and reinstall a new sealing diaphragm 200; the sealing gasket 210 is made of polytetrafluororubber, has good elasticity and sealing performance, and good corrosion resistance, and can ensure that the sealing diaphragm 200 completely seals and separates the first flow channel 110 and the second flow channel 120.

In one embodiment, a fixing gasket 230 is further sandwiched between the sealing diaphragm 200 and the fixing member 220. The fixing gasket 230 can protect the sealing diaphragm 200 from being squeezed and damaged by the fixing member 220, and improve the installation stability of the sealing diaphragm 200, thereby increasing the service life of the sealing diaphragm 200 and ensuring that the sub-control valve has Good reliability in use.

The structure of the electric explosion drive device is described below in conjunction with FIG2. In this embodiment, a mounting hole 105 is provided on the valve body 100, and the electric explosion drive device is threadedly connected to the mounting hole 105. The mounting hole 105 is arranged opposite to the sealing diaphragm 200 and coaxially with the first flow channel 110, and the piercing member 31 is also located on the center axis of the first flow channel 110, so that the electric explosion drive device can drive the piercing member 31 along the center axis of the first flow channel 110 to pierce the sealing diaphragm 200, and its stroke is the shortest, which can shorten the response time of the sub-control valve.

The electric explosion drive device comprises an electric explosion tube 300 threadedly connected to the mounting hole 105, the electric explosion tube 300 has a mounting inner cavity 302, the end of the electric explosion tube 300 close to the mounting hole 105 has a through hole 301 for the piercing member 31 to pass through, the end of the electric explosion tube 300 away from the mounting hole 105 is provided with an electric explosion firing structure, the mounting inner cavity 302 is slidably connected with the piercing member 31, and the electric explosion firing structure can drive the piercing member 31 to approach the sealing diaphragm 200 when it is activated. One end of the electric explosion tube 300 is provided with an external thread that cooperates with the mounting hole 105. When the electric explosion firing mechanism is activated, the piercing member 31 can be driven to pass through the through hole 301 and pierce the sealing diaphragm 200. The electric explosion drive device thus arranged has a simple structure and is more compact in the axial direction, which can reduce the volume occupied by the sub-control valve.

Please continue to refer to Figure 2. The above-mentioned installation cavity 302 has a limiting step 303. The above-mentioned puncture member 31 includes a connected sliding portion 311 and a puncture portion 312. The above-mentioned sliding portion 311 is slidably connected to the above-mentioned installation cavity 302.

One end of the elastic member 330 abuts against the lower wall of the sliding portion 311, and the other end abuts against the limiting step 303, which can prevent the puncture member 31 from approaching the sealing diaphragm and piercing the sealing diaphragm when the electric explosion firing structure is not started, thereby ensuring the reliability of the use of the sub-control valve; at the same time, the elastic member 330 can also rebound the puncture member 31 to its original position after the puncture member 31 pierces the sealing diaphragm 200, thereby ensuring that the rupture on the sealing diaphragm 200 is in an open state, thereby ensuring smooth flow between the first flow channel 110 and the second flow channel 120.

In one embodiment, the electric explosion firing structure includes an igniter 321 and an expansion agent 322. A mounting groove 3111 is provided at the top of the sliding portion 311, and the expansion agent 322 is placed in the mounting groove 3111. When the igniter 321 is activated, the expansion agent 322 can be ignited, and the high-pressure gas generated by the explosion of the expansion agent 322 pushes the piercing member 31 toward the sealing diaphragm 200, thereby piercing the sealing diaphragm 200; the mounting groove 3111 is provided at the top of the sliding portion 311 to accommodate the expansion agent 322, which can shorten the axial length of the electric explosion driving device, thereby reducing the volume of the sub-control valve.

In one embodiment, the puncture portion 312 is provided with a blind hole, and the outer peripheral wall of the puncture portion 312 is provided with a liquid discharge hole 3121 connected to the blind hole. The puncture portion 312 provided in this way can use the liquid discharge hole 3121 to play a role of liquid discharge and flow diversion after the puncture portion 312 punctures the sealing diaphragm 200, thereby ensuring that the first flow channel 110 and the second flow channel 120 are connected in a very short time, thereby shortening the response time.
